Chapter 1 Overview
1-1. Special Features
The SH11 Series uses a high precision interpolation circuit to achieve an insertion error
of 0.1 µm or less within a scale engraving pitch of 16 µm.
The output signal is a 5 V line driver, so it can be connected directly to a numerical
controller to provide position feedback.
Installation is easy for this unit-type scale. For scales with a measuring length of
520 mm (20.47 in) or more, use standard accessory support bracket A or B to increase
the rigidity at the intermediate position.
Wide Variation
Twenty measuring lengths are available in the range of 70 to 1,240 mm (2.76 to 48.82
in).
Choose the optimum scale length to match the required stroke.
High Precision
The scale precision is as follows.
• Measuring length 70 to 620: ± 2 µm
• Measuring length 670 to 1240: ± 3 µm
Excellent Resistance to Working Environment
The detector component employs a large-area optical exchange device using Moiré
interference fringes. Employing our unique stable Moiré detection system, the effects of
dust can be minimized and reading errors reduced.
Durable Construction
The detector component employs sturdy, precision die-cast aluminum, making it
possible to obtain stable Moiré fringes. A bearing guide system enables maintenance
of ideal traveling conditions.
Minimum Wiring
Position detection signals are provided for only the following three pairs.
• Position signal.............. A phase, A phase, B phase, B phase
• Zero point signal .......... Z phase, Z phase
Each of these employs the noise-resistant line-driver method.
Simple Maintenance
The detector component is designed to be replaceable, so if a problem occurs, the
scanning unit can be speedily replaced and normal operation resumed.

1. The installation side is marked ▼.
2. The screws shown in the drawing are included.
3. A support bracket or brackets are required for scales with
a measuring length of 520 mm (20.47 in) or more.
4. A type or B type support brackets can be selected.
5. The zero point signal is output when the on the scale
is approximately aligned with the on the scanning unit.
6. If the scale is moved beyond its measuring length, it will
)
be damaged. Therefore, take steps to ensure that the
stroke of the machine ends 10 mm (0.394 in) or more to
the inside of both ends of the measuring length.
